Over the first five years of owning her car, Gina drove about 12,700 miles the
first year, 15,478 miles the second year, 12,675 the third year, 11,850 the fourth year, and
13,075 the fifth year. a. Find the mean, median, and mode of
this data.
b. Explain which measure of central tendency will best predict how many miles
Gina will drive in the sixth year. a. | mean = 12,700; median = 13,156; no mode; the mean is the best choice because it is
representative of the entire data set. | b. | mean = 13,156; median = 12,700; mode = 3,628;
the median is the best choice because it is not skewed by the high outlier. | c. | mean = 13,156;
median = 12,700; no mode; the mean is the best choice because it is representative of the entire data
set. | d. | mean = 13,156; median = 12,700; no mode; the median is the best choice because it is
not skewed by the high outlier. |
